Description
Proton decay in three-generation superstring models with intermediate scale is investigated. It is shown that matter-parity (M2) invariance alone does not stabilize the proton. However, models with M2 invariance and Calabi-Yau manifolds such that the exotic C-odd quarks and leptons are superheavy will generally lead to proton lifetimes consistent with existing data
